Oracle Business Intelligence 11.1.6.0 – Master Detail Data Linking

Master-detail linking of views allows you to establish a relationship between two or more views such that one view, called the master view, will drive data changes in one or more views, called detail views.

This is an attempt to explain how to setup and invoke master detail events on views.

Master Detail Linking

Assume that we have two views; one view which shows revenue by product lines while the other graph view that shows revenue by months with year on a section slider. Using the master-detail linking functionality one can link these two views so that when you click on particular year, the year on the section slider of the graph as well as the data in the graph changes to reflect the year that was checked on the table.
